1203BB DC Motor Speed Controller - The 1203BB DC motor speed controller uses Pulse-Width Modulation PWM to adjust the speed of a DC motor or other DC loads. It provides a continuous current of 3 A to the connected load. - Forward, reverse, and stop functions are controlled via a switch, allowing bidirectional operation and easy stopping of the motor. - Input power range: DC 6 to 28 V, enabling compatibility with common batteries and power supplies. - The circuit includes a 3 A fuse, and the forward/reverse direction and motor stop are controlled by a switch for straightforward operation. - Use scenarios: - Build a small robot or chassis that requires bidirectional drive and adjustable speed, powered from a 6-28 V source. - Create a hobby RC vehicle or rover where simple direction control and speed modulation are needed. - Implement a compact automation component such as a small conveyor belt or actuator that runs from a DC supply within the 6-28 V range and draws up to 3 A.
